About Vanessa Nefflen, M.A.,

At Keystone Fiduciary Services, I am dedicated to promoting clients’ security and enhancing their quality of life. This commitment is backed by decades of experience as a licensed fiduciary, disabilities advocate, and mental health clinician. After graduating with distinction from Northern Arizona University with a Master’s in Psychology, I made Flagstaff my home and devoted my career to improving the lives of my community members. I have built strong professional relationships with a wide network of service providers and have extensive experience working with the Division of Developmental Disabilities. My expertise includes advocating for and supporting individuals with intellectual and developmental disabilities, as well as aiding those facing emotional and behavioral challenges.

My fiduciary career began at the Coconino County Public Fiduciary office, where I served as a Guardian and Conservator, and later expanded into the private sector as a founding partner of a fiduciary group. Keystone Fiduciary Services is founded on a deep commitment to ethical standards, prioritizing the welfare and security of our clients.
